Hi all, I am a homeowner in NJ who does all my own work on my 9000 square foot lawn consisting of a mixture of fescues, ryes and KBG variants. The lawn has a lot of deep shade in the back and north side, and sun/shade elsewhere. I am not a licensed pesticide applicator. I'm always seemingly behind the curve in terms of weed control and am constantly overseeding. This year I'm really hoping to get a head start on things and not be as far behind the 8-ball in 2014. I buy almost everything from JDL, and this year's Dimension+fert application is working wonders, but along with the turfgrass I got some bittercress popping up, and seedheads for something I can't identify, mostly along the curb line. Foxtail, too, I suspect. I hit the bittercress and a few small broadleaf plants with Bonide's Weed Beater Ultra (a slightly-hot mixture from concentrate @2oz/gal). Killed the flowers in a day and the plants are yellowing but not dead yet. I know from experience that by late July I will have plantain up the wazoo, despite heavy core-aeration last year and overseeding--there are still bare spots that never germinated after that overseeding--that I want to fill in later this year. The Dimension application prevents me from doing this at this juncture, of course. So all that background leads to my main question. I'd say my lawn is about 90+ percent weed free at the moment and all I do is spot treat as I see them pop up. What are the major differences in weed control that the selective herbicides a professional applicator would use (3-way, Momentum, etc) versus what is available to the homeowner? Would there be any benefit to calling in a pro for a broadcast treatment with stuff I can't use myself or am I best off just alternating treatments with Weed Beater Ultra and Weed-B-Gon Max in a handheld pump sprayer as need arises? Are the professional strength products' weed killing properties that much better than what's available to me or is it mostly an issue of cost-effectiveness to turf professionals who require high volumes of product for their hundreds of customers? I still have some timeline questions for this year that I'll post separately, but I'm really curious about the efficacy of consumer products. Cost isn't an issue. Safe and effective weed control is. Thanks in advance.
